no idea how to make a omlette (its fucking hard) but it was OK. I blended the eggs with heavy cream so they dont get rubbery even if you over cook it.
That was probably a bad move - you'd more likely end up with scrambled egg, and if you like colour in them it would be hard to achieve. Eggs (scrambled) cooked in cream are a thing, but omelette isn't.
The omlette is easy to do, but you really need a non-stick pan. If you're sure your pan is non-stick and the omelette is sticking, it's not been done long enough. Which would also be suggested by the pale look.
As you'll have seen above, my particular requirement was a French omelette, and those are meant to be not browned. But American omelettes are a bit different and easier. Start with your eggs (three are good, two if you're experimenting in a small pan) and blitz them. I have an electric cocktail stirrer I use - it's possible to do by hand with a fork or whisk, but 10krpm with a small beater is better. Salt and pepper to taste. Nothing else - no cream, milk, water (although, if you must, half a teaspoon is OK). If you're intending to throw in chillies, ham, or similar, don't - just get to making the omelette before screwing it up with additions
Next, blob of butter (lightly salted is good, but whatever your taste is) in the pan which should be hot enough to have the butter bubbling but not browning. At that point, pure in the eggs and give them a good stir. Leave to stand for 30 seconds so the base forms, then use a spatula (or fork) to drag in the sides so you build up cooked egg in the middle and runny egg takes its place around the sides. Once the new stuff is set, repeat until you have no more running egg. Almost done.
If you lift the edge of the omelette all the way around, the entire thing should move if you shake the pan. You can peak underneath to see if it's brown enough for you, and when done just flip one side over on top of the other. Slide onto place. Eat.
For cheese and stuff you want as a filling (as opposed to mixed in), plonk it in what will be the bottom half when the egg is set but it's not met your colour preference yet. If you want you can cover the half a bit early, then when the bottom is done flip it all over so the new bottom (which was the top) now gets finished. That will give the filling time to really melt.
Lots of video on Youtube for reference, but if one is saying to add milk, cream, water or anything except more eggs to the eggs, ignore it and move on.
